The portable radio/speaker can be charged in 3 ways: solar powered, self-winding or with the supplied USB cable. With the radio you can receive both AM and FM radio stations. You can easily use the radio as a power bank thanks to the included USB-C cable. With a capacity of 1000 mAh, your phone will be charged again in no time! The built-in flashlight is useful when it starts to get dark and you're still on the road or if you've lost something. The unit has an IP64 coding and is therefore dust and splash-proof. So you can use it in all weather conditions. The radio is also no bigger than a Smartphone and you can easily take it with you wherever you go. A handy device for when you go camping, hiking, when you travel, but also for real emergencies!
